The Staubli MC4PR-6I-10PK is a pack of ten Original MC4 solar connector pairs, each pair holding one plug and one socket rated for DC 1100V under IEC 62852. The MC4PR-6I-10PK crimps onto 4mm² and 6mm² solar cable with an outer diameter of 5.0 to 6.0mm, using Staubli's MULTILAM contact system. These connectors also carry UL 6703 approval to DC 1500V and TUV Rheinland certification for photovoltaic use.
Rooftop solar wiring lives outdoors for the life of the array, so every connector on a string has to hold up to UV, heat, and moisture without letting joint resistance climb. The MC4PR-6I-10PK supplies ten matched pairs in one box, which suits a full string run or a service van restock without ordering sockets and plugs separately. Each connection uses the MULTILAM contact band for contact resistance under 0.25 milliohm, holding output steady across the system's service life. The connectors carry an IP65/IP68 mated rating and a -40°C to +85°C operating range for exposed array conditions.
Solar installers reach for the Original MC4 because most panel and inverter makers fit it as standard, so a genuine Staubli connector matches the joint already on the array. The open crimp contact crimps in one action with the matching Staubli tool. The locking latch needs a release tool to open under NEC 2023, which stops accidental disconnection on a live string. A 10-pack format keeps unit cost predictable across a job and leaves spare pairs in the van for repairs. Rated to 39A under IEC 62852, one pair suits typical residential and commercial string currents.
The MC4PR-6I-10PK is not a pre-made lead and needs the correct Staubli crimp tool and proper cable stripping for a compliant termination. It is not rated for indoor AC wiring or any use outside DC solar strings, and should not be mated with another brand's connectors, as cross-mated PV joints are a known fire risk. The 6I seal only accepts 5.0 to 6.0mm outer-diameter cable, so other cable sizes need a different seal.
(MC4PR-6I-10PK)
The MC4PR-6I-10PK is certified to IEC 62852 and TUV Rheinland (R 60127190), and is listed under UL 6703 and CSA C22.2 No. 182.5 on file E343181. It also holds JET certification (B19T0013) for photovoltaic use at its rated DC voltage.
Solar connector termination should be carried out by a licensed solar installer or electrician. Each contact crimps onto stripped PV cable with the matching MC4 crimp tool, then clicks into the insulator until the latch locks. Correct strip length and crimp tool are needed for a compliant, weatherproof joint.
Staubli advises mating the connector only with suitable connectors from the Original MC4 family. Mixing brands of PV connector is a known cause of hot joints and rooftop fires, because contact shape and plating differ between makers. For a safe joint, keep both halves genuine Staubli MC4.
The 6I connector crimps onto 4mm² and 6mm² solar cable with an outer insulation diameter of 5.0 to 6.0mm, using a 5.8mm crimp opening. Cable outside that outer-diameter range needs a different MC4 seal size to keep the gland weatherproof.
Staubli builds the Original MC4 for low performance loss across the connector's service life, backed by over 30 years of field use. The connectors handle -40°C to +85°C ambient, carry an IP65/IP68 mated seal, and are rated for up to 100 mating cycles. Tin-plated copper contacts resist corrosion at coastal and rural sites.
The open crimp contacts need an MC4 crimping tool sized for 4-6mm² contacts to form the joint. Once mated, the locking latch needs an MC4 spanner or release tool to separate, which meets the NEC 2023 tool-to-open requirement. Protective caps are advised for any unmated connectors.
The MC4PR-6I-10PK contains ten connector pairs, each pair being one plug and one socket, for twenty connectors in total. They are supplied as open crimp connectors for field assembly, not as pre-made leads, so each one crimps onto your own PV cable on site. Cable and crimp tool are not included.
